Abstract

This article is divided into two parts. In the first part a process flow diagram for the production of Acetone was designed with Aspen HYSYS. Acetone obtained is 94.6% pure and the designed plant is safe to environment with less emissions. In the second part HEN (Heat exchanger networks) was developed for the process plant by performing pinch analysis using Aspen Energy Analyzer. Retrofit analysis was applied to find an alternative HEN which saves the energy of the process by minimizing the operating costs. In retrofit mode four new heat exchangers are added to the base case HEN which reduced the operating cost with the payback period of 0.72 years.
